AbstractIntroduction: The baseline radiographic defect angle has previously been correlated with the clinical outcomes of intrabony defects treated with access flap or guided tissue regeneration. The aim of this study was to investigate whether an association exists between baseline radiographic defect angle and treatment outcome when enamel matrix derivative (EMD) is used in periodontal regenerative surgery. Materials and Methods: Baseline radiographs were collected from the test group of a previously published clinical trial using a population of 166 patients treated for chronic periodontitis. All intrabony defects were ≥3 mm for inclusion in the original study. Either modified or simplified papilla preservation technique was used to access the defect. The roots were conditioned with an EDTA gel and the primary outcome measure was clinical attachment level (CAL) change, 1 year after surgery. Results: Sixty-seven radiographs were measurable. The probability of obtaining CAL gain > 3 mm was 2.46 times higher (95% confidence interval: 1.017-5.970) when the radiographic defect angle was ≤22° than when it was ≥36°. Conclusions: This study showed that there was a significant association between baseline radiographic defect angle and CAL gain at 1 year. The observed increased odds ratio of obtaining CAL gain of ≥4 mm after regenerative surgery with EMD is used in narrow (≤22°) intrabony defects, suggests that the baseline radiographic defect angle might be used as a prognostic indicator of treatment outcome. © Blackwell Munksgaard, 2004.
